Szárnyprofilok
Szárnyprofilok, often translated as airfoil, are the cross-sectional shape of a wing or a fin. This specific shape is crucial for generating lift and controlling aerodynamic forces when an object moves through a fluid, most commonly air. The fundamental principle behind airfoil function is the difference in air pressure created above and below the wing's surface. Air traveling over the curved upper surface has to move faster than the air traveling under the flatter lower surface. According to Bernoulli's principle, faster-moving air exerts lower pressure. This pressure difference results in a net upward force, known as lift, which opposes gravity and allows aircraft to fly.
The design of an airfoil can vary significantly depending on its intended application. Factors such as the
